To all whom t may concern:

vBe vit known that'I, HUsToN TAYLOR, a

citizen of the United States, and residing 'at Redford, in the county of Wayne and State of Michigan, have invented. a new vand Improved Automatic Oil-Lubricator, lof which the following is a specification.' l

My invention relates Vto improvements in oil lubricators which are ycarried on partslof a machine or vehicle, particularly on'motor driven vehicles, wh1ch`a`re subjected to 'jars and vibrations, and the object of my inven-v tion is toprovide an oil reservoir in' which oil is sustained by atmospheric pressure-and from which it `may flow to the part to be lubricated, according asy air isV admitted to'v said reservoir, and means to regillate the admission of air.

I attain this object by the Yconstructions illustrated in the accompanying drawings;

Vhen `sufi cient oil has been shaken or splashed out of the containerzB, so .-thatlthe level of the oil in itfis below Vthe opening yor outletifrom Vthe reservoir, .air is'admitted tosaid reservoir until suiicient oil has poured into con;`

-tainer B to liftthe -level or lsurface eleva. vtion as toclose'outlet D. of the .reservoir againstfurther'admission of air.

;Fig. .5,A shows a horizontal sectionzof the.y construction illustrated in Fig. l in a line across the bayonet clutch J, illustrating the clutch .moref fully .and showing the screwl driver slot K in the end of threaded stem E,; l

which slot facilitatessecuring of the `lubricator in place. N j [Figaro showsla slight modification of the bayonetslot connection illustrated. in` F ig.` 1, iii that the slot is in this instance inclined, which' facilitates an adjustment fof eleva-v tionfbetween aperture D of reservoir A and cov The washer or wickinggg/inr container Bl isshown closing aperture D of reservoir,v to oder frictional resistance to the discharge of oil from said reservoir under the conditionsV of Vibrations andjarsto which itis subject. Under the impulse of the momen: tum in sudden vertical Vibrations'more oil islikelyr to bedischarged than desired, under which condition if the oil is held: to; the opening-by a wicking, itisless liable3 to admit air when the oil level in container B really does not warrant it.

I do not limit myselfy to these-v construe-VY tions but they are suiiicient toshow my in- Vention.

To operate my invention vfill with liquid oil, secure in proper place ona machine to be lubricated, and: subject it to.l jars andl v-ibrations;

I claim:

l. As an article of; manufacture7 ann'oil y cup; having a threaded: hollow stemf forming a duct, said oil cup; including a container communicating with the ductand also including ak sealed reservoir` aboyethe con.- tainer'and opening' thereimthehquid in the container forming a seal. for the:y outletfrom` the reservoir.

2. Asa unitary article of manufacturaan oil cup having af. reservoir in which oil is sustainedby, atmospheric pressure, said oil eupF also having anoil. container below the reservoir and supplied with oil therefrom, said oilI cup including aA hollow threadedstem through whichi oil is: restrictedly.y fed: to ay part to be lubricated.

3; As an article ofV manufacture, anyoil cup including a reservoir anda container immediately below the reservoir and? athin dividingy wall forming: the bottom of* the cup to a: part' tot be lubricated and for conducting'` oil"V from the container.

4". A cup-shaped lubricator incllldinga closed, upper chamber for lubricating fluidi and a lower chamber separated by aA partitionY that'dips into thelowerchamber4 and forms a seal with lubricatingrfluidtherein, said lubricator ber whereby'it' maybe-attached to arpart to be lubricated andi throughy which oilfmay befed from said lower chamber.

5. As anarticle off manufacture, an: o1l cup 'forming-v a reservoir closed at'V itsy upper including-- 'af perforated threaded stem leadingv from" the lower cham-h endv and a container communicating therewith, an outlet for the container at a point above the outlet from the reservoir to said container, the oilV cup forming an air chamber between said two outlets, the parts beingso constructed and arranged that oil may be shaken from the container through the irst namedY outlet.

6. An o il cup, including a container having a passage through which oil is shaken to a part to be lubricated, aclosed reservoir connnunicatingwith the container-at aipoint slightly below the point at which thepassage connects with the container,- said container forming a closed air chamber except insofar as it communicates with the reservoir and the passage, whereby the level of` oil'- in the container is normally maintained slightly below theentranceto the passage.

7. In a. lubricator, an oil reservoir constructed of two cup-shaped metal stampings having the openends of each permanently closed by theother, said reservoir having an aperture at the lower end eccentric toits. circular end, acup-shaped support for they reservoir, said aperture being normally closed by oil standing inL an annular groove in the cup-shaped support. e

8. In lubricator, an oil reservoir in which oil is sustainedy by atmospheric pressure, said reservoir having an aperture,

another container adapted to contain oil byl which said aperture is closed, a wick to which oilmayv be shaken from ther second container, said wick being normally out of communication with; the supply ofr oil in thee lubricator.

9. As an article of manufacture, anl oil cup; including Aa. reservoir closed at its upper en@ and adapted tofretail oil therein by atmospheric pressure, said oil cup Aalso including a passage through which oil iiows from said-reservoir'by gravity, said passage including a portion beyond itspoint; of connectionff with the reservoir and higher than said point of connection, throughwhich portion: oil isz shaken fromfthe cup" in the normal' operation thereof.

10;.. As anarticle of manufacture, an: oil

cupincludingfa: reservoir closedl at its upper reservoir and for permitting oil to'be` gradually shaken from the cup inthe normal operation thereof.
